1. Hoarse voice: Lung cancer spreading to the lymph nodes can affect the vocal cords, causing hoarseness.
2. Coughing up blood: Lung tumors can irritate the bronchi and result in a persistent dry cough, sometimes accompanied by blood in the phlegm.
3. Facial swelling: Lung tumors can compress the superior vena cava, leading to facial swelling, neck edema, and swelling in the upper limbs.
4. Shortness of breath or wheezing: Tumor growth can narrow airways, causing symptoms like difficulty breathing. Seek medical attention if these symptoms persist.
